It's the properties of polymers, certain kinds of large molecules, that make these products bouncy, slimy, stretchy, breakable, hard, soft, sticky, moldableâand just plain fun to play with. Polymers are found in a variety of materials that have a broad range of properties.
As most dentists recommend, the best way to prevent a cavity is by brushing one's teeth twice a day with a fluoride toothpaste, flossing and rinsing with an oral rinse. As the tooth begins to decay more severely, there are several treatments that a dentist can use to attempt to repair the tooth.
If decay from a cavity progresses to the point where the pulp is infected or inflamed, an endodontist may save the tooth by doing a root canal. Endodontic treatment involves drilling through the enamel and down to the root canals. The endodontist removes the pulp containing nerves and blood vessels with tiny tools and brushes. The empty space is filled with gutta percha, a natural form of rubber.
